When you hit the ground. While they are falling they are in the air, and falling in and of itself will not kill you. The impact will always kill you -- unless you have a heart attack during the fall.
Imagine you are waiting for someone to jump from a high height, like the minimum height required for death upon impact. Imagine they get close enough to touch without falling on you, you aren't in the way. They are in arms reach, and before they reach the ground, you break the momentum with a horizontal shove, their body instead flies in a horizontal direction, and then down. Would the momentum be so broken that the velocity isn't enough to kill anymore?
THE QUESTION: 2) A 5 kg object is thrown from the top of a building, 275m aboce some level ground. It is released at a speed of 45 m/s, initially along the horizontal direction. (A) What are the magnitude and direction of its velocity at impact on the ground below (B) what momentum does it have at impact (C) What KE does it have just before impact (D) What is the average force during the impact?
Yes. Hitting water from even relatively low heights is usually fatal.
Because it is elastic, so little energy is lost in the impact . The kinetic energy it has immediately before impact is temporarily stored in the ball as potential energy, then released when the elastic material reforms into its previous shape.
The fright of falling may trigger a heart attack or some other form of stress related injury, but those are isolated cases. Upon impact, your bones would shatter, wounding all material around it, causing instant death. I don't know about you guys but i would crap myself.
The impact force depends upon the height from which it has fallen (IE- its velocity upon impact), and the duration of impact (determined by the elasticity of the collision). However, the object exerts no force upon the ground *while* falling.
It is unlikely that a glass will break before it hits the ground. The glass may experience tiny fractures which will cause it to break upon impact.
Its probably the impact
cartels are formed by the impact of falling object from space. since most of the objects disintegrate into fragments on or before entering the earths atmosphere it do not make any noticeable impact. hence cartels are rare.
on the ground!
Apparently some of the people who jumped were on fire so they might have died from the fire before they hit. Although, most were alive and healthy as they were falling right up until they hit the ground, where as my friend said after viewing the bodies, they were puddles of blood, and tattered clothing.
The American colonists began to experience vaginal bleeding, which caused their penises to turn slightly purple in color before falling off.
There are theories that many people, particularly those with a bad heart, die before hitting the ground due to the shock and terror of the fall itself, although this is really difficult to determine since it is impossible to predecit the exact second a person dies (whether they die just before impact from a heart attack, or the impact itself).
If you somehow go close enough to do so, yes. What we call falling stars are not actually stars but meteors, small bits of rock burning up in the atmosphere. As these rocks it the atmosphere they heat up to thousands of degrees before disintegrating. Such small fragments are destroyed long before they reach the ground. Larger meteors can reach the ground to become meteorites. Strangely, meteorites are usually rather cold at impact, as the passage through the atmosphere is too brief for heat to reach inside larger rocks. Very large meteors release a tremendous amount of energy and can be quite destructive.
He will throw impact exeplosives at you catch them before they hit the ground and then throw them back at him it's really simple
An impact.
The acceleration of gravity is 32 feet per second, per second. This means that --eliminating any obvious aerodynamic considerations as there would be with, say, a feather -- the speed at which an object falls increases proportionately to the time it is falling. An object falling from a greater height will be falling for a longer time period and thus will reach a higher velocity and impact the ground with a greater force than one falling from a lower height.
